It’s been over a month since Zayn Malik left British pop group One Direction. Since the split, the rest of the 1D boys have been better than ever, completing their tour and continuing to work on their upcoming fifth album. Malik, meanwhile, has been hanging out with (irrelevant) music producer Naughty Boy, allegedly working on a solo project. Since Malik picked NB over 1D, it has been no secret that there are hard feelings between the parties, with words being exchanged on Twitter here and there over the past few weeks.

Today, 1D’s Louis Tomlinson absolutely slayed Naughty Boy via Twitter, and this time Malik himself got involved in the scuffle. Earlier today, Naughty Boy posted a photo to Twitter of himself with Malik, with the caption “Replace this.” Tomlinson fired back, “Remember when you were 12 and you used to think those Mac filters for your pictures were cool haha ! Some people still do HA!”

Tomlinson and Naughty Boy went back and forth for several tweets, attacking each other’s careers, with Naughty Boy claiming that Tomlinson “can’t even sing”:

Never fear, sassy Louis put NB in his place, but the most heartbreaking part of the whole feud came when Malik himself got involved, questioning Tomlinson and his “bitchy comments”:

This is especially upsetting to 1D fans, because when the break-up initially happened, it seemed that Malik was leaving for his own well being and had no ill feelings toward his bandmates and “brothers”. Malik calling out Tomlinson via Twitter, and not even defending him against Naughty Boy, shows that perhaps there are hard feelings existing between Malik and the rest of the 1D boys.
